Hey Shane, I'd recommend some sort of short term financing with using your personal assets as the collateral or something besides that specific property as collateral.

Sure, no one has to accept any specific offer...calling for highest and best doesn't mean they have to choose highest and best, just that they're saying they want to make sure everyone has put their best foot forward.

In most jurisdictions when you rent a SFH everything on the lot is included unless specifically excluded in the lease.  

and is this your thought on my situation specifically, being a total beginner?

You're right, a CPA would be able to answer your specific tax questions, but I do know that as a single member LLC, the default tax status is disregarded entity.

What you can do is filter for that specific amenity and see how well booked the calendars of those listings are.

Like, digging into specific sub-markets and getting that super detailed intel requires more than just surface-level stuff.

A good lender or loan officer will see your specific financial profile, tell you what is and isnt possible, and ultimately should give you suggestions on what to aim for and focus on so that you can get what you need to eventually be ready to purchase. 

While I have basic underwriting skills for mobile home parks, I would like to gain a working knowledge of the specific steps needed to make a solid offer on an RV park.

Have something specific in mind?
